Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
lookup_crawler reads unknown never probed
Look up a documented crawler on Rattlesnakes By Mail by name, slug, or user-agent string, and return identity fields, current claims, publication dates, and evidence URLs. Use lookup_crawler when the crawler is already named, or when the user agent is already known to belong to a documented crawler.
identify_user_agent reads unknown never probed
Match an unrecognized raw User-Agent header against the crawlers documented on Rattlesnakes By Mail, and return the matched crawler plus instructions for verifying the request. Use identify_user_agent when the crawler behind the User-Agent header is not yet known.
list_changes reads unknown never probed
List recorded changes to claims on Rattlesnakes By Mail, newest first, with the change date and the affected crawler. Filter by date with since, by crawler with entity, or by both. Use list_changes to detect crawler policy updates published after a given date.
ask reads unknown never probed
Match a free-text question against the claims published on Rattlesnakes By Mail, and return the matching claims, or no match when no published claim covers the question. Every question sent to ask is recorded, and a recorded question may be published on the public questions page at Rattlesnakes By Mail. Do not send private or identifying text to ask.
submit_note changes data unknown never probed
Submit a correction or note about a claim, an entity, or a question on Rattlesnakes By Mail. Requires a client token issued out of band by the publisher. Every note is stored as pending, and an editor reviews every pending note before publication.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idc8b64c397f7719b7.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/c8b64c397f7719b7/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
